tailieunhanh - (1,7,4) Data hiding scheme for searching in hidden text with automata
In this paper, we present a new data hiding scheme (1,7,4) for grayscale images, where 7 is the number of pixels in each block of the image, 4 is the number of secret bits which can be hidden in each block with restriction that at most one pixel is changed, and the gray value is changed at most 3 from the original one. | (1,7,4) Data hiding scheme for searching in hidden text with automata
